I have been on Zwift for over a year now and I love the cycling. There is so much to do and I find the races and events entertaining and I plan to get more into the workouts now that you have training plans. The scenery also plays a big part in the enjoyment…making even a leisurely ride seem like I am going somewhere and with sound included, basically interacting with the environment around me.
Lately I have been trying the running…or actually walking. I have a very wonky knee and about 3 mph with some treadmill elevation is basically my max speed. I truly wish I could go faster but even at that speed I have difficulties. So, I am slow but even at full running speed I cannot see it being very exciting to run a few miles vs the cycling experience over the same amount of time spent. My suggestion is just speed the runners up. Runners won’t be competing with riders head to head so there is no need for them to have the same mileage and when the runners are on the course the mileage can be adjusted to fit them. So if the distance from the Italian Village to the finish line is 3 miles (?) for the cyclists then for the runners it could be 2 miles or whatever. This would speed them up on the course but keep their mileage accurate. I think this would make the running experience more interesting and also bring more of the Zwift experience into play.
